Statistics of Galactic-scale Quasar Pairs at Cosmic Noon [PDF]
Astrophysical Journal, 2022 The statistics of galactic-scale quasar pairs can elucidate our understanding of the dynamical evolution of supermassive black hole (SMBH) pairs, the duty cycles of quasar activity in mergers, or even the nature of dark matter, but they have been ...

Identification of tagged glycans with a protein nanopore
Nature Communications, 2023 The structural complexity of glycans seriously challenges the currently available analytical methods. Here, the authors report the identification of glycan isomers, glycans with varying chain lengths, and distinct branched glycans, via a glycan ...

Matrix Factorization Techniques in Machine Learning, Signal Processing, and Statistics
Mathematics, 2023 Compressed sensing is an alternative to Shannon/Nyquist sampling for acquiring sparse or compressible signals. Sparse coding represents a signal as a sparse linear combination of atoms, which are elementary signals derived from a predefined dictionary ...

Comparative roles of charge, π, and hydrophobic interactions in sequence-dependent phase separation of intrinsically disordered proteins [PDF]
Proceedings of the National Academy of Sciences of the United States of America, 2020 Significance Mesoscopic condensates of proteins and nucleic acids, including membraneless organelles, serve myriad biological functions, whereas dysregulation of condensates can cause disease.

Stochastic dynamics of single molecules across phase boundaries
Physical Review Research, 2021 We discuss the stochastic trajectories of single molecules in a phase-separated liquid, when a dense and a dilute phase coexist. Starting from a continuum theory of macroscopic phase separation we derive a stochastic Langevin equation for molecular ...

Statistics of the separation between sliding rigid rough surfaces: Simulations and extreme value theory approach [PDF]
, 2019 When a rigid rough solid slides on a rigid rough surface, it experiences a random motion in the direction normal to the average contact plane. Here, through simulations of the separation at single-point contact between self-affine topographies, we ...

Generalized Spatio-Temporal RNN Beamformer for Target Speech Separation
Interspeech, 2021 Although the conventional mask-based minimum variance distortionless response (MVDR) could reduce the non-linear distortion, the residual noise level of the MVDR separated speech is still high. In this paper, we propose a spatio-temporal recurrent neural

A survey for large image-separation lensed quasars [PDF]
, 1996 The statistics of gravitationally lensed quasars with multiple images in the 0.1''-7'' range have been measured in various surveys. Little is known, however, about lensed-quasar statistics at larger image separations, which probe masses on the scale of ...
